The championship was held under the new unified SpeedSeries banner, promoted and organized jointly by Motorsport Australia and the Australian Racing Group.
Particularly the eligibility rules for a Supercar license de facto mandating a stint in the Super2 series were accused to draw interest away from the S5000 championship.
[4] All teams competed with identical Rogers AF01/V8 single-seater racecars, Ligier/Onroak chassis powered by Ford Coyote V8 engines.
After two years of holding the main S5000 season and the S5000 Tasman series as separate championships over five and two rounds respectively, this changed in 2023.
[25] The 2023 season kicked off in late February at Symmons Plains Raceway with 88Racing's defending champion Joey Mawson on pole position.
His advantage was short-lived, however, as Mawson took the lead right at the start of the first race and never looked back from then on to take his fourth straight win.
The third race was comparatively calm, with Webster fending off Mawson at the start and showing superior pace from then on to take the win.
Mawson made a clinical restart to claim the win, while Golding failed to warm up his tires, running off track to hand podium spots to Webster and his teammate Blake Purdie.
Championship contender Webster returned to the series and was right back at the front, taking away Cameron's lead into turn one starting the first race.
His win saw him start from the front for race two, in which the top four cars of Webster, Cameron, Boys and Purdie all held their position throughout the encounter.
Webster's pole position for the main event was challenged by 88Racing's Aaron Love, before Cameron slipped past both of them to take the lead.
With his sights set on the championship title, he crushed his opposition through the first race to win lights-to-flag ahead of Boys and Purdie.
The final race saw another controlled lights-to-flag effort by Cameron, who therefore became just the third driver to win both the MA Gold Star and the Tasman Cup in the same season.
